Thus, before the intelligent device 200 has been loaded on the mobile working machine 100, the cushion springs 241 enable the floating base 231 to be in a preloaded state, that is, the cushion springs 241 mutually provide a uniform force for pushing the floating base 231 towards the notch 221 so that the outer rim portion 232 of the floating base 231 is pushed to abut against the adjoining surface 222F of the third groove 222 without being randomly swayed.
The floating base 231 further includes an annular protrusion 234 and a plurality of second through holes 237. The annular protrusion 234 is formed on one surface of the protruding body 233 being opposite to the outer rim portion 232 to surround and define a sunken portion 238. Furthermore, one surface of the annular protrusion 234 being opposite to the sunken portion 238 is further formed with a guided slope 235. The second through holes 237 are spaced arranged in the sunken portion 238 according to the predetermined arrangement mentioned above. The second conductive contacts 280 respectively, for example, are conductive posts, and embedded in the second through holes 237, respectively. One end of each of the second conductive contacts 280 is soldered to the second circuit board 250, and the other end is projected into the sunken portion 238 from one of the second through holes 237. The second fastening portion 260 includes two hooking portions 270. The hooking portions 270 are respectively formed on the annular protrusion 234, for example, the hooking portions 270 are respectively disposed in two trenches 236 which are arranged oppositely on the annular protrusion 234. The second conductive contacts 280 are located between the hooking portions 270. Each of the hooking portions 270 is pivotally connected to the second main body 210, that is, each of the hooking portions 270 is rotatably disposed in one of the trenches 236 for being engaged with one of the position-limited slots 161. For example, each of the second conductive contacts 280 includes a spring connector 128 (e.g., Pogo Pin). Each of the spring connector 281 can be compressed to be shortened in length, and will be restored to the original long form by its resilience when it is no longer compressed. The resilient force of the spring connector 281 is less than the resilient force of each of the cushion springs 241.
In addition, in the embodiment, the second connection module 230 further includes two elastic members 239 respectively located in the floating base 231. Each of the elastic members 239 is connected to the floating base 231 and one of the hooking portions 270, respectively, that is, each of the elastic members 239 is disposed within one of the trenches 236 and abuts against the bottom of one of the trenches 236 and one of the hooking portions 270, respectively. For example, each of the elastic members 239 is, for example, a compression spring or the like.
For example, more particularly, each of the hooking portions 270 includes an L-shaped member 271, a pivot shaft 272 and a hook body 273. The L-shaped member 271 has a first rod body 271A and a second rod body 271B which are adjoined to each other. The long axis direction of the first rod body 271A intersects the long axis direction of the second rod body 271B. Each of the elastic members 239 abuts against the second rod body 271B and the floating base 231. The pivot shaft 272 is disposed on a junction portion of the first rod body 271A and the second rod body 271B, and is used to pivot the L-shaped member 271 to the floating base 231. The hook body 273 is disposed on the first rod body 271A of the L-shaped member 271 so as to be removably hooked on one of the position-limited slots 161. The hook bodies 273 of the hooking portions 270 are faced to each other.
FIG. 5A-FIG. 5D are continuous schematic views expressing the intelligent device 200 being loaded on the mobile working machine 100. As shown in FIG. 5A and FIG. 5B, when the intelligent device 200 of FIG. 5A is desired to be loaded onto the mobile working machine 100, the intelligent device 200 is first descended vertically to the first top portion 111 of the mobile working machine 100. Next, through the guiding of the guiding slope 235, the annular protrusion 234 of the intelligent device 200 starts to insert into the surrounding groove 143 of the mobile working machine 100, and the hook body 273 of each of the hooking portions 270 starts to contact with the guiding portions 162 of each of the position-limited slots 161. (FIG. 5B). Next, when the intelligent device 200 continues to push the mobile working machine 100, the guiding portions 162 of the position-limited slots 161 pushes the corresponding hooking portion 270, so that the hooking portion 270 starts to rotate about the pivot shaft 272 (FIG. 5C), and the hooking portion 270 starts to compress the corresponding elastic member 239. At this moment, As shown in FIG. 5C, the first conductive contacts 170 respectively contact with the second conductive contacts 280. Since the horizontal gap 224 is formed between the inner side surface 221F of the notch 221 and the protruding body 233. In this embodiment, since the horizontal gap 224 described above is formed between the receiving recess 220 and the floating base 231, the floating base 231 can horizontally correct the dislocation between the first conductive contact 170 and the second conductive contact 280 in the horizontal direction. Next, when the hook body 273 of each of the hooking portions 270 starts to reach the slot inlet 163 of the corresponding position-limited slot 161 from the guiding portion 162, the resilient force of the corresponding elastic member 239 rotates the hook body 273 of the corresponding hooking portion 270 into the slot inlet 163 to be engaged with one of the position-limited slots 161. Thus, the second bottom portion 212 of the second main body 210 is fixedly coupled to the first top portion 111 of the first main body 110. In this moment, as shown in FIG. 5D, the first conductive contacts 170 are respectively compressed by the second conductive contacts 280 to be tightly contacted with the second conductive contacts 280. Thus, since the cushion module 240 causes the second conductive contacts 280 to continuously press the first conductive contacts 170 downwardly, the bonding force of the intelligent device 200 to the mobile working machine 100 further allows the second conductive contact 280 to firmly press the first conductive contacts 170.
It is noted, since the arrangement positions of the first conductive contacts 170 and the second conductive contacts 280 are designed in correspondence to the first fastening portion 160 (FIG. 2) and the second fastening portion 260 (FIG. 3), thus, once the first fastening portion 160 and the second fastening portion 260 are mutually engaged with each other, the first conductive contacts 170 can be effectively aligned with and connected to the second conductive contacts 280.
In addition, as shown in FIG. 5D, after the intelligent device 200 is loaded on the mobile working machine 100, a vertical gap 225 is formed between the adjoining surface 222F of the third groove 222 and the outer rim portion 232 of the floating base 231. Since the horizontal gap 224 and the vertical gap 225 are disposed between the receiving recess 220 and the floating base 231, the cushion module 240 can absorb the vibration generated by the mobile working machine 100 during traveling, so as to reduce the risk of the intelligent device 200 falling from the mobile working machine 100.
On the other hand, FIG. 6 is a schematic view of the intelligent device 200 of FIG. 1 being removed from the mobile working machine 100. As shown in FIG. 5D to FIG. 6, when the intelligent device 200 of FIG. 5D is desired to be detached from the mobile working machine 100, the intelligent device 200 is first vertically ascended relative to the mobile working machine 100 so that the adjoining surface 222F of the receiving recess 220 of the second main surface is ascended to the outer rim portion 232 of the floating base 231, thereby pulling the floating base 231 upwardly; at this moment, the floating base 231 pulls the hooking portions 270 with the elastic members 239 as linkage members. Thus, since the hook bodies 273 are respectively blocked by the position-limited slots 161, each of the hooking portions 270 starts to rotate about the pivot shaft 272 (FIG. 6) until each of the hooking portions 270 completely disengages from the position-limited slots 161 (FIG. 5C). Thus, when the second main body 210 is separated from the first main body 110, the second conductive contacts 280 are separated from the first conductive contacts 170 (FIG. 5A).
FIG. 7 is a partial cross-sectional view of the intelligent device 201 being removed from the mobile working machine 101 of the detachable robot system 11 according to one embodiment of the disclosure.

The first magnetic body 180 is completely buried inside the first main body 110. For example, the first magnetic body 180 is embedded in the internal of the material body of the first main body 110 and is adjacent to the surface of the first top portion 111 of the first main body 110, but is not exposed from the surface of the first top portion 111 of the first main body 110. The intelligent device 200 further includes at least one second magnetic body 290. The second magnetic body 290 is completely buried inside the second main body 210, and aligned with the first magnetic body 180. For example, the second magnetic body 290 is embedded in the internal of the material body of the second main body 210 and is adjacent to the surface of the second bottom portion 212 of the second main body 210, but is not exposed from the surface of the second bottom portion 212 of the second main body 210. When the first fastening portion 160 and the second fastening portion 260 are engaged with each other, with the first magnetic body 180 and the second magnetic body 290 are magnetically attracted to each other, the second bottom portion 212 of the second main body 210 can be more tightly coupled to the first top portion 111 of the first main body 110.
FIG. 8 is a partial cross-sectional view of the intelligent device 202 being loaded on the mobile working machine 102 of the detachable robot system 12 according to one embodiment of the disclosure. As shown in FIG. 8, in the embodiment, the detachable robot system 12 of FIG. 8 and the detachable robot system 10 of FIG. 1 are substantially the same, however, at least some differences of the detachable robot system 12 of FIG. 7 from that in FIG. 1 are that, the hooking portions 270A and 270B are symmetrically arranged with each other, and the hook bodies 273 of the hooking portions 270A and 270B are faced away from each other, that is, the hook bodies 273 of the two hooking portions 270A and 270B respectively extend towards away with each other. More specifically, the first rod body 271A of the hooking portion 270A is farther away from the first rod body 271A of the other hooking portion 270B than the second rod body 271B of the hooking portion 270A. The first rod body 271A of the hooking portion 270A is farther away from the second conductive contacts 280 than the corresponding elastic member 239. The two position-limited slots 161A are oppositely formed on opposite sides of the surrounding groove 143, and the opposite sides of the surrounding groove 143 respectively face the projection portion 141 with each other.
In each of the aforementioned embodiments, the mobile working machine 100 is a vacuum sweeping machine, and the dust sweeping machine has a dust suction opening (not shown in figures).
